In this activity we are exploring the SAS Triangle Condition in Spherical Geometry. Adjust the[br] two lengths for the sides of a triangle and the measure of the included angle [br]by the sliders and/or input boxes. [br][br]Are there any conditions where there is no triangle possible for the [br]chosen measurements? If so, what conditions do the measurements have to have in [br]order for a triangle to exist?[br][br]If such a triangle exists, then how many different congruence classes [br](different sizes of triangles) may result? [br][br]In Spherical Geometry, if two triangles exist and they have two corresponding pairs of [br]congruent sides and the corresponding pair of included angles are congruent,[br]do the two triangles have to be congruent?
